PICK COUNTER LOOMS.

provement in pick counters for looms. ln

the pick counter illustrated in my Patent No. 1,478,908, dated December25, 1923, the counting mechanism was supported on a bracket consistingof a strip of flexible metal fastened at one end to the arch of the loomframe, and at the other end to the counting mechanism.

This bracket was twisted between its ends so that lateral vibrationsWere taken care of my the flat in one pla-ne While the longitudinalvibrations Were taken care of by the fiat in the other plane. .This pickcounter has been satisfactory in operation and large numbers oi pickcounters. embodying this invention,

lhave been put in use.

The present invention is an improvement on the construction of thecounter of the patent.

In it provision is made for absorption of vibations both longitudinallyand laterally and a more compact and eiicient construction has beenproduced.

The invention consists in a pick .counter hereinafter described andparticularly defined in the claims.

In the accompanying drawings illustrating the invention, Fig. 1 is afront elevation of a part ofa loom showing one form of the invention inposition thereon; Figs. 2 and?) are similar views, omitting loom parts.of

form of the invention,

tional elevation taken on the line 9v-a9 Fig 8.

The first form of the invention illustrated in Figs. 1, 4iand 5 isdescribed as follovvs. The counter proper 10 is connected by theflexible drive shaft 11 with the reducing mechanism 12 which is mountedupon the crank shaft 13 of the loom. To the arch 14 on the loom isattached the counter support rod 15. This counter support consists of arod received in a hole in the flange 1b of the arch 14 and securedthereto by means of nuts 17 Which are .screwed up against lock washers18 on opposite sides of the flange 16 of the arch. Thisprovides a firmattachment of the counter support to the loom frame. The counterl() hasal casing 19 upon the top of which is a cylindrical boss 20. The boss isprovided with a longitudinal hole 21 reduced in size at 22 to slidnglj'receive the support rod 15. The

`hole 21 is closed by the collar 23 which is forced into the open end ofthe hole ivith :i drive lit. The support is provided with a transversepin 211 the lower end of which projects into the groove 25 in the boss20. On each side of the pin 2&1 are :'vprings 26 of such `lengththaifthey are under compression when they are assembled. The parts areput together by inserting the rod in the hole in the boss in the countercasing with the tivo springs in position on it. then the collar o3 isforced into the open end of the hole 21 thereby securing the parts inplace. The springs `26 being under compression balance each other andhold the counter in position on the rod with the springs in equilibrium.Longitudinal vibrations of the loom frame are transmitted. of coin-sc,to the support 15 but that support may move longitudinally in thecounter boss and While some movements of the counter may occur theheavyjars and vibrations of the loom frame are not transmitted to thecounter yexcept through the springs 26 which yield in operation owing tothe inertia of rest of the counter. The slot which .receives the ,2 yisWider than the pin as a result otf which the; frame. of the loom mayvibrate forwardly and backwardly without imparting other than slightmovements to the counter, the capacity of the counter to turn upon therod permitting it to occupy a` position of balance on the rod from whichit hangs. The longitudinal vibrations of the loom are more serious thanthe forward and backward vibrations of the loom and the counter iscushioned against the transmission to it of the longitudinal vibra-tionsby means of the springs. The lateral or forward and back vibrations ofthe loom are less severe and their direct transmission to the counter isavoided by the construction by which the counter is permitted to turnupon its support. In setting up the counter, the pin 24 of the supportrod 15 should occupy the center of the slot 25 in the boss on thecounter casing so that the counter may be permit-ted to have freeoscillatory movement about the support within the limits ermitted by thedifference between the width of the slot and the thickness of the pin.The center of gravity is below the position of the support 15 as aresult of which the center of gravity of the counter may remainsubstantially stationary even with considerable oscillations due to theforward and backward movements of the loom frame.

In the second form of the invention the counter 30 is supported on thesupport rod 31 in a manner somewhat similar to that of the first form ofthe invention above described but with these differences; instead ofreceiving the support 31 in a boss on the top of the counter casing thesupport is received in a sleeve 32 carried by the casing side 33. Thissleeve 32 forms a support for one set of counting wheels 34. The ends ofthe sleeve 32 project beyond the casing sides 33 and are embraced bycollars 35, these collars fitting over the ends of the sleeve with adrive fit. Each collar is provided with a notch 36 to receive a. springend 37. The support rod 31 lits loosely in the center openings in thecollars. Springs 38 embrace the support rod 31 and their outer ends 37project into the notches and collars as above described. The inner endsof the springs 38 are received in notches 39 in the enlargement 40 ofthe support rod 31. This second form of the invention is assembled asfollows With the sleeve 32 in position in the counter and the outsidecollar 35 in place the support rod 31, carrying its springs 38, isinserted through the left hand end of the sleeve 32. The end 37 of theright hand spring is inserted in the hole 36 in the right hand collar35. The other collar 35 is slipped over the end 37 of the left handspring 38 and forced with a tight fit on the end of the sleeve 32, thecollar and sleeve 32 are thereby rigidlyl attached to the counter. Thesprings provide both for longitudinal movement of the counter on thesupport rod 31, holding the counter in equilibrium between the pressuresof the two springs, and also permit, owing to the torsional resilienceof the springs, oscillatory movements of the counter on the rod 31. Uponreference to Fig. 2 it will be seen that the center of gravity of thecounter 30 is below the support rod 31 as a result of which forward andbackward movements of the loom and consequently such movements of thesupport 31 tend t0 oscillate the counter on the in 31 rather than tocause it to partake o the forward and backward movements of the supportrod 31. i

In the third form of the invention the counter 5() is supported on abracket 51, having a journal 52 which receives the counter support rod53 secured to the flange 16 of the arch of the loom. The counter 50 isbolted by means of the bolt 54 to boss 55 on the bracket 51, the counterand bracket being carried by the rod 53 and permitted to movelongitudinally of the rod and to oscillate thereon. A spring pin 56 isrigidly secured at one end in a hole in the support rod 53. The otherend of the spring 56 is loosely received in a hole in the arm 57 whichforms a part of the bracket 51. The spring is of steel wire and permitslongitudinal vibrations of the loom frame to occur while the counterstands fast. It also permits forward and backward movements of the loomframe while the counter 50 itself stands fast, the spring permitting alimited movement of the loom frame with respect to the counter so as toprevent the transmission of vibrations, both longitudinally and forwardand backward, from the loom frame to the counter.

In each of the constructions above described it will be observed thatlongitudinal vibrations of the loom frame are only transmitted to thecounter proper throu h springs which reduce the severity of t evibrations received by the counter and thereby preserve it from thesevere blows, vibrations, or shocks in a longitudinal direction.Similarly, in each case the center of gravity of the counter is offsetfrom the support upon which the counter is carried so that the forwardand backward movements of the support will be permitted without beingtransmitted with force to the counter itself. In each case forward andbackward movements or vibrations or blows of the loom frame permitoscillating movements of the counter with respect to its support.

Having thus described the invention, what is claimed is 1. A pickcounter for looms, comprising a counter proper provided with a parthavmg a bearing, a support for attaching the counter to the frame of theloom having a portion arranged longitudinally of the loom to be receivedin the bearing of the counter, and spring means to resiliently resistrelattive longitudinal movements of the counter and its support.

2. A piek counter for looms, comprising e counter proper and a supportfor att-aehing the Counter to the fra-me of the loom7 the eonntei` beingpivotelly and slidingly mounted on the support to have iesilientlyresisted capacity for movement longitudinelly of the loom and a Swingingmovement in a plane at right angles to such movement.

In testimony whereof I have signed my name to this specification.

ALBERT HAYES MORTON.
